CABLE-SPLICE.

Application led December 12, 1913.

l poses and which has high resistance.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawing forming a part of this specification, and in Figure 1 is a longitudinal section of a splice embodying my invention, and Fig. 2, a section taken on line -m of Fig. l.

The preferred form of construction `as illustrated in the drawing comprises two lead casings or tubes 1 and 2 which are secured to the endsl of the ordinary lead pipe or casing 3 surrounding the cable sections, said cable sections being provided with the usual insulation 4 andthe wire 5. Each of the casings 1 and 2 is secured to the corresponding lead pipe 3 by means of a wiped soldered joint 6 as shown.

A metallic socket member 7 is secured to the end of one of the wires 5l and a metallic plug 8 is secured to the end of the other wire 5 and is adapted to fit within socket member 7, plug 8 being provided with transverse slits 9 to afford resiliency thereto andy thus effect a good electrical connection. A tube 10 of insulatingmaterial is arranged in casing 2 surrounding member 7 and the insulation 4 as shown, said tube extending to the end of socket member 7. The portion of plug 8 adjacent the endof the corresponding wire is covered with an insulation 1l which may be of insulating tape if desired, said insulation 11 extending about half the length of plug 8 so as to leave a portion of said plug protruding for entry into socket 7. An insulating tube 12 is tted 'over in-v sulating tube 10 and projects around insula-v tion 11 so as to further insulate the connection and to break or cover the joint between insulating tubes 10 and 1l. Another insulating tube 13 is placed in casing 1 around the usual insulation 4 as shown.

Specification of Letters Patent.

Serial No. 806,175.

This arrangement effects an insulation of the joint between the wires of very high resistance. y

.A threaded head 14 is soldered tothe end of casing 2, the end l5 of said casing being upset against the end of said head as shown to further strengthen the connection. An other head 16 is soldered to the endxof casing 1 with the end 17 of said casing upset over the end of head 16 to strengthen this connection, A threaded sleeve 18 is swiveled to head 16 and threaded on head 14 to effect a swiveled threaded union between said heads to hold said parts together. A gasket 19 of rubber or other suitable material is interposed between the upset ends 15 and 17 of casings 2 and 1 respectively so as to insure the forming of a water tight joint. By this arrangement a connection between the ends of wire sections 5 is effected which may be readily detached for testing purposes and which has greatV resistance to the escape of current and is also perfectly water tight.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this' is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to availinyself of such variations and modifications as come within the scope of the appended claim.

Having described my invention what I claim as new and desire to secure by Letters Patent is: j

, A device of the class described comprising two cable sections, lead pipes encircling said cables, a casing section of larger diameter secured to the end of each of said pipes, means for securing the ends of said casings together, a socket member secured to the end of the wire of one cable, a plug secured to the end of the wire of the other cable section, a tube of insulating material surrounding said socket member throughout its length and extending over the entire portion of the respective cable end within the casing member, a similar tube having one end thereof arranged between the last mentioned tube and the casing and projecting beyond said socket member, insulation inclosing said plug except the portion adapted to fit within said socket, the ,end of said insulation being adapted to abut the end of the socket member andthe tube immediately surrounding the same, insulation arranged between the cable end bearing the plug and its respective casing member and the projecting end of the insulating tube on the a' socket end adapted to extend over the insulation on' the plur and adjacent portion of the cable and abut the last mentioned insulation, substantially as described.

In testimony whereof I have signed my WILBUR O. WILSON.
